I have a 3 yr old home and it appears when the "plumbers" installed my tub
they used a prybar in the drain to position it and cracked it. They then
hired a professional to repair it. Well, it started leaking from the
upstairs to my bathroom downstairs. I couldn't find it so I replaced the
qauter round and re caulked it. The put in a shower door. I'm thinking the
whole time that my teenagers are just being sloppy and it's leaking around
the tub because I couldn't see it in the tub. And when I disassembled the
faucet/shower I couldn't find a leak. I kept looking and decided to re
putty the drain. It still leaked. That's when I finally noticed the
hairline border around the repaired crack! arrgghh. Of course I contacted
the builder and they had a good laugh I'm sure.

anyway, the crack appears to be about 2" long on the floor of the tub and
about 1/2" wide in the center. I have to assume it goes down the drain as
well because the leakage slowed considerably when I reputtied it.

For now I just want to stop the leak with some adhesive. The tub is you
basic molded plastic/fiberglass(?) shower/tub combo. I imagine in the
future I will have to rip it out and put in a completely different type of
tub, unless I decide to take the dorr out to fit a molded one back in.

Any and all suggestions are appreciated and welcome.

thanks, Bill
